Sir Bernard Katz

Born 26 Mar 1911.German-born British physiologist who elucidated how nerve cells transmit signals to muscles. Although it was known that neurons release acetylcholine at their terminal ends, Katz discovered in the early 1950s that the release of this neurotransmitter occurs continuously and spontaneously, although at low levels when neurons are at rest. Further, he found that acetylcholine is released in discrete packets, later called vesicles. In the late 1960s, Katz determined that the amount of acetylcholine in a vesicle was related to the electrical potential at the terminal of an axon (the long extension of a neuron that transmits the impulse). These studies won him a share (with Julius Axelrod and Ulf von Euler) of the 1970 Nobel Prize for Physiology or Medicine.

Good News, Bad News

A minister stood in front of his congregation and announced, "I have good news and bad news. The good news is we have enough money to pay for our new building program. The bad news is that it’s still in your pockets.”
